Thank you for taking the time to report this bug and helping to make Ubuntu better. It sounds like some part of the system has crashed. To help us find the cause of the crash please follow these steps:
1. Look in /var/crash for crash files and if found run: ubuntu-bug YOURFILE.crash Then tell us the ID of the newly-created bug. 2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us. 3. If step 2 also failed then apply the workaround from bug 994921, reboot, reproduce the crash, and retry step 1. Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself. ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1781826 Title: System logout when turn off the screen or suspend Ubuntu 18.04 Status in gnome-shell package in Ubuntu: Incomplete Bug description: When turn off the screen or suspend, and resume the system is logged out, this mostly happens with nvidia driver (390 or 396). I noticed that when close the lid and reopen the system is still working and all of a sudden it appears a login screen and when login all programs as killed as it was logged out. And most of times after login it locks and prompts an unlock screen. I tried to switch to nouveau driver and the problem seems not to happen, but that leaves me with a poor performance in terms of graphics. I tried to reset the setting in dconf using dconf-editor to reset the system recursively, at the beginning seems to be solved but it gets back. I need to mention that I faced the same problem when using budgie flavor, I thought that it might be a budgie problem but it appears to be a gnome problem since budgie is based on gnome and on both the problem happens when using Nvidia drivers. --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.2 Architecture: amd64 CurrentDesktop: ubuntu:GNOME DisplayManager: gdm3 DistroRelease: Ubuntu 18.04 NonfreeKernelModules: nvidia_modeset nvidia Package: gnome-shell 3.28.2-0ubuntu0.18.04.1 PackageArchitecture: amd64 ProcVersionSignature: Ubuntu 4.15.0-29.31-generic 4.15.18 Tags: bionic Uname: Linux 4.15.0-29-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.2 Architecture: amd64 CurrentDesktop: ubuntu:GNOME DisplayManager: gdm3 DistroRelease: Ubuntu 18.04 NonfreeKernelModules: nvidia_modeset nvidia Package: gnome-shell 3.28.2-0ubuntu0.18.04.1 PackageArchitecture: amd64 ProcVersionSignature: Ubuntu 4.15.0-29.31-generic 4.15.18 Tags: bionic Uname: Linux 4.15.0-29-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.2 Architecture: amd64 DisplayManager: gdm3 DistroRelease: Ubuntu 18.04 NonfreeKernelModules: nvidia_modeset nvidia Package: gnome-shell 3.28.2-0ubuntu0.18.04.1 PackageArchitecture: amd64 ProcVersionSignature: Ubuntu 4.15.0-29.31-generic 4.15.18 Tags: bionic Uname: Linux 4.15.0-29-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1781826/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
